To all? whom may come/m:

Be it known that lr., DDN A. SARGENT, e citizen of the Uniteti States,residing et; Bangor, in the county' of Penobscot, State ci Meine, haveinvented certain new end useful improvements in Truck Snowpiovvs; and ldo hereby declare the following to be e full, olea?, and exactJdescription of the invention, such as Will enable others skilled in the:ii't to which it epperteins to make and use the same.

This invention relates to snow plows, and iii particular to plowsdesigned to vbe secilecl to motor trucks,

Wiliere stieets or roadways ere filled with Y very deep 'or driftedsnows, e.. powerful tractor drawn plow, such as desciiaed anti claimedin my copendiiig application, Serial.

It is en object of the present invention to. improve the iiesgn of suoliplows so that motor vehicles, particularly trucks, mcy be iisetl, notonly for the general Weiz: of eleeiqu snow-bound. tlioioiiglifores, butmay equipped with their own szooiv ifemovicg ai pei'atus. haveaccordingly piovitietl e plow having a. frame designed to ce secuieii toboth miles of e truck, so that tlie snow resistance is distributed; thisfijeme being iesigneii for loci@ longitudinal and trees verseetliistmeiit tc lit any chassis. lieve designed lie frame to hang belowthe axles, eind ce sec-ciecl to the axle in such manner that there is oodirect three?, on this; smic.

Besides these things, I lieve .meile improvements in variousdetails, 'which will be pointed out in the following ciescifiption, iiiwhich., for the seize of cleainess, l( have mede reference to tlieeccompeiiying cire-e ings, which illustrate. av preferred embofiiment omy invention.

cui'eel to the axles, The forward ends ci the siti-e, members 3 areformed of channel irons 105 else itung beneath and secuietl to the iontaisle of the truck by means of Ufoelt cleinps ll. The weer ends of theselongituciii .il side members eie termed of Wooden l2, which fitisetvveen the iieoges of the lic chennelsQ and are heldin piece byIneens of U-bolt clamps 13. The length of the freine v with an eye y26onV each erin 7.

may thus be varied within wide limits by loosening the clamps 13, byextending or telescoping the members 9 and 12 relative to each other.The transverse members [l ere provided with a series of holes 14:through which bolts 15 are adapted to poss and secure the members l tothe upper flanges of the channels 9. It is thus obvious that the widthof the fremsmey be varied to suit trucks of various Widths.

The rear end of. the freine is secured to the .rear axle by a speciallydesigned-nlsmp, which l shall now describe. Pistes 16 end 17 bolted `tothe upper and lower feces' respectively of the members 12 extendlTeerwerdly therefrom,` and terminate in. hinge knuckles Y18. Upon theseknuckles are hinged 2 upstanding lates 19 sind 21; plete. 21 beingcurved, es s'iown, in order to more securely the usuel curved faces or"the rear exile housing. These plates i9 and :2l are held fest to theaxle by' means of bolts 22, which pass through them vend on either sideof the axle. When these bolts are tightN ened and the U-bolt clamps 13mede to hold the members 9 and inI reletively'iixed relation, it isclear that the snow resistance is distributed between the two axles. 1tis ini-s portant, however, that the rear eide, with, its enclosedtransmission, should be protected. from sudden shocks, which mightotherwise injure it. Assuming, therefore, that the l bolt clamp 11 works,loose or is not sucient to absorb a sudden shock, the plates 19 ond 21swing slightly about the hinge knuckles 18, and thus relieve the sxle ofthe shock. At the seme time, however.' this movement by tending todistort-,fthe ligure *formed by the pistes 19 and 21 and the bolts 22will tighten the grip of these members upon the rear axle.

shell now describe the manner which. the nose is connected to the treme.The nose is secured/to 'the iframe through the arms 2' .which take thethrust of the snow'. The noseis provided at either side with s. pair ofeyes 25,-whicli are normelly in alignment A pin 27 passes through theseeyes and holds the ports in position. There is, however74 Sullicientlooseness et this point to permit e. sub-y stantial up and down movementof the noserelative to the frame.A Should the use of' the nose, nolonger be vrequired, it can be swun (Y beck out of operative positionand carried upon the frame, es indicated in dotted lines in Fig. 2, b vmerely withdrawing the pins 27 and swinging the nose back upon the forward end of the freine, as shown in dotted lines in Fig. 2, a. pair ofcrossed chains 24;, connectin the rear of the nose with the freineacting es hinge members.

l shell now describe the wings, which may be employed in cooperation wh"he nose. These wings 6 ere provided their forwerd ends with eyes 2S,which are brought in alignment with the eyes 25 end 26, end held inposition by means of the pins 27'. Lateral adjustment oi these wings toincrease or decrease the width of the pothfto be plowed is edectedthrough the bersf. pivoted et 31, neer the outer end of each wing. Thesebers are supported by ineens of guides or brackets 32 bolted to thelower enge of the clisnnels 9. Bars 29 ere )roe vided with specedholes'y 'through w ich pins een be passed to beer against the chennels 9end hold the wings in adjusted position. When the nose is swung intoinoperative position by removing the pins 27, it is, oi

course, customary to remove thev wings etV the saine time.

The plow einhodying the subject metter of this invention is simple endrelatively in-l expensive to construct; 1s reeldily attached to truc-ltsof verious sizes, distributes the snow pressure between' the two axleswithout sub jecting the resi: axle to the danger oic bres."- ege throughsudden shocks', can plow e ,oath of varying width dependingnpon'thesetting of the wings,-end can he readily end quickly dismantled es s4plowing machine with minimum ci ed'or l claim:
